As per title, everytime I reboot proxmox I am losing network connection and access to the GUI. Any idea if anyone had this before and how to solve this?

Did run a
Code:
ifup vmbr0
error: vmbr0: bridge port enp4s0 does not exist

Code:
#etc/network/interfaces

auto lo
iface lo inet loopback

auto enp4s0

iface enp4s0 inet manual

auto vmbr0
iface vmbr0 inet static
    address 192.168.0.11/24
    gateway 192.168.0.1
    bridge-ports enp4s0
    bridge-stp off
    bridge-fd 0

iface wlp3s0 inet manual

this was working fine before I rebooted

Note: Did find the solution. The enp4s0 changed to enp3s0 for some unknow reason after reboot. Anyone can explain why?

How i fixed it, in case anyone have this issue, run:

Code:
ls /sys/class/net

should show the enpXXXs0, change it accordingly in your etc/network/interfaces file
